If a Planetar Angel and an Elf had a child?

[Vec]

What would the offspring of a plantar angel and an elf be?

My group and I just finished the rise of the rune lord adventure path and one of the characters had a celestial joining after the big baddy was beaten and went to live in heaven with his wife, the plantar angel.

I would guess it would be a Half-Celestial (http://www.d20srd.org/srd/monsters/halfCelestial.htm) Elf.

Ever since they printed their species specific Half Fiend template (Monster Manual Web enhancement (https://www.wizards.com/default.asp?x=dnd/we/20060630a)), I have used species specific Half Celestials too.

Half Planetar:
As Half Celestial except as follows:
+4 natural armor (instead of +1 natural armor)

Can swap any Half Celestial spell-like ability for a Planetar spell-like ability of comparative utility (daily limit of 1/day or 3/day remain)

Abilities: (these replace Half Celestial's modifiers)
Str +6, Dex +0, Con +2, Int +4 Wis +4, Cha +4
[Half Planetars are stronger(+2Str) and more intelligent(+2Int) but less agile(-2Dex) and less hardy(-2 Con) than the common half celestial]
